How to annoy an Aphra

I like to observe how people use language, and tend to neither prescribe nor proscribe. However, some new usage does manage to scrape on my nerves. The first two dislikes are business-speak, the third is general. All three seem to be increasing.

Prior instead of before

Mutiple instead of several, many or some or a straight-forward plural

Myself instead of me or I

I hadn’t noticed them prior to this, but they are increasingly used in multiple situations by others but not by myself.
